Nerve allograft reconstruction of digital neuromata

Abstract

Objective: A symptomatic digital neuroma may have a devastating impact on a person's life. There is no gold standard method of treatment. We hypothesise that the reconstruction of neuroma with nerve allograft will reduce the sensitisation and cortical reorganisation associated with peripheral nerve injury. In this study, we aim to assess the effect of neuroma reconstruction with nerve allograft on patient-reported pain and satisfaction. Methods: We conducted a retrospective review of patients who underwent nerve allograft reconstruction for painful digital neuroma at our unit, from July 2015 to July 2018. We measured pre- and post-operative visual analogue scale (VAS) pain scores, patient satisfaction and patient evaluation measure (PEM) scores. Results: In 10 patients, we reconstructed 12 neuromata. In nine of these patients (11 neuromata), we demonstrated a post-operative reduction in pain, with a change in median VAS score from 7.5 to 1. Patients were satisfied with their operation, with a median satisfaction score of 10/10. The procedure was unsuccessful in two patients, one with a static VAS score and one with a satisfaction score of
